Auroral oval layers detection by using CSES plasma and electric field data

Ionospheric medium fluctuations are detected at various spatial and temporal scales. Plasma irregularities encountered crossing high latitude current systems can be extremely thin and, therefore, unlikely to identify with standard detectors. This work aims to show plasma layer features obtained by electric field instrument on-board the Chinese Seismo Electromagnetic Satellite while crossing the equatorward boundary of the auroral oval allowing the characterization of its various layer. In addition, we made the multi-scale statistical analysis in order to describe the fluctuations of the ionospheric medium.
